BALL OR BULLET.

SPECIFICATION forming part of Letters Patent No. 795,088, dated July 18, 1905.

Application filed October 29, 1902- Serial No. 129,211.

To all whom it 1mty concern:

Be it known that I, HENRY (J. AsPiNwALL, a citizen of the United States, and a resident of Haskells, in the county of Passaic and State of New Jersey, have invented a new and useful Ball or Bullet, of which the following is a specification.

My invention relates to a ball or bullet, and more particularly to that class of balls or bullets which are known in the art as covered balls or bulletsz7. 6., bullets in which the body consists of lead or other suitable heavy soft metal with a thin covering of harder metal such, for example, as cupro-nickel.

In order to prevent the powder from escaping along between the interior wall of the bore of the gun and the exterior wall of the ball or bullet covering, it has been found desirable to attach to the base of the ball or bullet what is known as a gas-check.

This has soft-metal body of thebullet.

Aside from the expense entailed in providing the saucer-like disks with screws and the labor entailed in fastening these to the bullets it has been found very difficultto attach these saucer-like disks absolutely concentric with the longitudinal axis of the bullet and in such true planes laterally as to efiectually shut off the escape of the burning gases and the consequent scoring of the bore of the gun.

My invention is directed to a structure which will overcome the defects of that or those hitherto employed; and it consists, broadly, in extending the covering of the ball or bullet beyond the heel end of the body of the bullet to form the gas-check, leaving its rear end free to expand under the pressure produced by the exploding charge and effectually prevent their passage past it.

which Figure 1 is a view, partly in section, of a cartridge, showing the covered ball or bullet in position therein ready for firing.

Fig. 2

is a rear end view of the ball or bullet. Fig.

3 is a view of the ball or bullet in side eleva- 5 tion. Fig. 4 shows the bullet as it appears during its travel along the bore of the gun, and Fig. 5 is a view of the bullet in longitudinal section.

The cartridge-casing (denoted by 1) forms no part of my present invention and may be of any well-known or approved form.

The body of the ball or bullet is denoted by 2 and its covering by 3. The covering 3 is extended rearwardly, as clearly shown in 6 Fig. 5, beyond the rear end of the body 2 of the bullet, forming the shallow cup-like extension 4 when crimped, as at 5, in proximity to the rear end of the body 2 of the bullet. This crimping of the cover 3 may be performed by machinery with the greatest accuracy, While the projecting rear end of the cover 3 is supported upon a suitable mandrel, thereby insuring the perfect centering of the part4 with respect to the body of the bullet, the 7 crimp 5 performing the doublefunction of holding the body 2 of the ball or bullet in position with respect to its cover 3, at the same time forming the contracted neck of the saucerlike gas-check 4:, which under the pressure of the burning gases in firing the gun will spread sufficiently to form a gas-check and prevent the passage of the burning gases past it. This structure does away entirely with the screw or other fastening heretofore attempted to attach the gas-check to the ball or bullet and saves time and labor both in the manufacture of the gas-check as a separate piece as well as in the assembling of the check and bullet as heretofore.

While I have shown the invention in connection with a cartridge such as is commonly used in small-arms, it is obvious that the invention is equally applicable to cartridges of such form and size as are used with larger 9 guns and cannon, especially those of the rapidfire type.

What I claim is A covered ball or bullet having its covering extended rearwardly beyond the rear end of the body of the ball or bullet and contracted enoe of tWo Witnesses, this 20th day of October, 1902.

at its base and a point forward of its rear end and in proximity to the rear end of the said body forming a cup the annular wall of which 7 will expand under pressure from the explosive l HENR1 ASPINWALL' charge to form a gas-check.

In testimony that I claim the foregoing as my invention I have signed my name, in pres- Witnesses:

FREDK. HAYNES, C. S. SUNDGREN.
